ASPHALTUM-COLLECTOR- FOR OIL-BURNERS.

SPECIFICATION forming part of Letters Patent No. 715,234, dated December9, 1902. Application led April 3, 1902. Serial No. 101,187. (No model.)

To @ZZ wiz/0191, it 17m/y concern:

Be it known that 1, GEORGE W. AEPEE, a citizen of the United States,residing at Oakland, county of Alameda, State of California, haveinvented certain new and useful lmprovements in Asphaltnm-Oollectors forOil- Burners; and I do hereby declare the following to be a ful-l,clear, and exact description of the same.

With the oil-burners in use at the present ti me for the utilization ofcrude or bituminous oil as afuelin connection with stoves, ranges,furnaces, &c., no means are provided for collecting or saving the baseor asphaitum of such oil. Consequently the base or heav7 residue ispermitted to carbonize and go to waste. The residuum of the crude oilincident to the State of California forms an excellent quality of pureasphaltnm having a high commercial value.

The object of the present invention is to provide an oil-burner forcrude oil with means for collecting the asphaltum contained therein.

To comprehend the invention, reference should be had to the accompanyingsheet of drawings, wherein- Figure 1 is a vertical sectional view of astove with the oil-burner andasphaltum-collector arranged therein. viewof the burner and collector removed from the stove, and Fig. 3 is alongitudinal sectional View on line :c m of the burner and collectorillustrated in Fig. 2 of the drawings.

In the drawings the numeral 1 is used to indicate an ordinarycooking-stove, and 2 the fire-box thereof, within which is arranged theoil-burner. The oil-burner comprises the repot 3, provided with theair-inlets 4. Into this pot oil is admitted through the oil-feed pipe 5,which leads from the outside of the stove. The feed of oil is regulatedor controlled by means of the valve 6. To obtain proper combustionwithin the fire-pot, a jet ofsteam is admitted to the oil flame'from thesteam-pipe 7.

Below the nre-pot. 3 is located a collectingreceptacle 8, the chamber 9of which communicates with the tire-pot 3. ln fact, in the present caseconnection between the fire-pot and the collectingreceptacle is made bymeans of the circularweb or neck 10, depending from and which maybe saidto constitute a downward extension or continuation of the bottom 11 ofthe nre-pot.

Fig. 2 is a detaily When arranged within the iire-box of a stove, thecollecting-receptacle is suspended .below the grate-line, it beingpreferably supported bymeans of projections 12.

The collecting-receptacle is provided with 6o a double inclined bottom13, the inclination being toward the center thereof, wherein is formedan outlet 14. This outlet is closed by a slide-gate 15, which gate isattached to the inner end of fulcrumed lever 16. end of this leverextends a slight distance beyond the collecting-receptacle. -The gate 15is held against downward movement, due to the pressure of the materialwithin the cham- The outer ber 9, by means ofthe supporting-stirrup 17.7o

This stirrup is arranged at a slight inclination, so that the gate isforced firmly to its seat, as thrown inward.

In operation thechamber 9 is first filled with crude oil, which isignited. Oil is then 7 5 admitted to the fire-pot through oil-feed pipe5 in order to supply the oil consumed in the collecting-chamber. As thelighter properties of the oil are consumed the heavier particles 0rasphaltum settle within the chamber 8o 9. After a firing of aboutforty-eight hours the chamber 9 will be filled with asphaltum, which maybe drawn od by opening the gate 15' and permitting same to escape into asuitable receptacle inserted within the ash-pit of 8g l the stove toreceive the discharge from outlet 14.

Having thus described the invention, what is claimed as new, and desiredto be protected by Letters Patent, is-

In combination with a stove having a firebox provided with suitablesupporting portions, a removable burner of the character describedadapted to be inserted into said firebox and comprising a lire-pot, afuel-inlet thereto, a collecting-chamber located therebeneath andconnectedV thereto by a hollow web or neck, a valved outlet from saidchamber, and lateral projections on said chamber adapted to rest uponthe supporting portions roo of the re-box, substantially as described.

In witness whereof I have hereunto set my hand.

GEORGE W. ARPER.
